full system (absolutely everything) backup

JUP — Wed, 30 Jul 2003 04:08:02 GMT

I have two indentical A Class 9000 systems running HP-UX 11.00

One is a master and one a standby (incase the master falls over). They share a common raid.

I wish to backup everything (except the mounted raid) from one system and restore it on the second system. I know the only difference should be the IP address which I can change manually once I restored it on the second system.

Is "dump" the best option to do this ? I want all device drivers, filesystems etc.

I think dump only does one file system but I need all filesystems on the one tape (ie. /scratch, /tmp, /usr, /var, /stand etc)

Any ideas would be appreciated.

Thanks in advance
PA

Hi,
Install Ignite and take a make_tape_recovery to backup the entire VG's or entire disk (-x option) and restore it to another system which is identical. Once restored reboot the system in single user mode and change the system name and IP address.

See man pages of make_tape_recovery for more help.

Hi

Ignite-UX is your best bet for this.
If its not installed you can install it from the application CD's.

Use the following command:
# make_tape_recovery -x inc_entire=vg00 -I -v -a /dev/rmt/0mn

This will backup your entire vg00 to tape and can then be restored to your backup A-Class server in case of failure.
Note the default tape device is /dev/rmt/0mn. You must specify a no rewind device.

Cheers

As Rajeev suggested, use ignite-ux to backup your vg00, eg.
# make_tape_recovery -AI

I assume that you installed other applications o other VG, then you may use other utillities such as tar, fbackup/frecover, cpio.. to backup other vg in which other applications existing. eg.
To store a particular directory:
# fbackup -f /dev/rmt/0m -i /tmp
or
# tar cvf /dev/rmt/1m /tmp (specify device)

To recover a particular directory:
# frecover -vx -i /tmp -f /dev/rmt/0m
or
# tar xvf /dev/rmt/0m /tmp

Hi,

The best and safer way by using Ignite, using tape_recovery.
In another way, If you are using any Backup Software like Omniback II or Veritas.
You can take disk image backup of existing node and same can be restored on disk of the another node.

By connecting root disk of second node to first/any other system, you can transfer the disk image. Later by connecting these disk to standby node, you can bring up.

Once myself followed above steps.

Thanks & Regds,
Rajesh
